Application filed February 15, 1911. Serial No. 608,777.

To all whom it may concern:

Be it known that we, lnrno M. BLACK MAN and WILLIAM MARsHA-Ln, citizens .of the United States, residing at El in, in the county of Kane and State of Illinois, have invented anew and useful Im rovement in Filling Apparatus for Liqui fReceptacles, of which the following is a specification.

()ur invention relates to an improvement in the class of filling apparatus used in 'a reservoir containing the supply of liquid (as syrup, milk or other bevere e) from whirh bottles and other forms of receptacle are filled in measured quantity by operating the apparatus, which comprises, generally described, a liquid holder or trap communirnb ing with the reservoir to be filled therefrom with a measured quantity of its contents and discharge the some through a valved outlet into a reeeptnele to be filled.

In the accompanying drawing, Figure l,

is a View in broken sectional elevation showing our improved filling upporutus in open :li lfl? position in a tank or reservoir; Figs.

2 and 3 are sections token, respectively, on

the lines 2 and 3, Fig.1; Fig. l is u vioiv in elevation 'of the valve-device and Fig. 5 is n-section on line 5, Fig. 1. through the mousure-reguluting tube.

A reser'voir (S is :1. usuul part of :1 iillin; machine equipment. inwhirh the reservoir is provided with a plurality of depending: valve-derives and is supported in etc-ruled vJn'tsitinn.over lhr purl of u lIHHlilHl (not shown) on which rrcoptiu'lrs to be filled, such as the rw-optuclo shown at 7 in Fig. l, are imposod to register with the rulvwdo vices, wlmrvby lowering the reservoir or rnising the romptueles engages with tho. lol- 1 her the valve-devices to open them and client the filling.

Our improvementrelates purtirulurl vto the valved and vented trap, of whirh only one is shown in the drawing, since they may all benlike if more than onev be employed.

The bottom of the reservoir contains an opening forming about its inner-end portion a downwardly-topering sent 8. in this sent. fits a correspondingly shug ed titmg'u. 9

formed about it, below cnmferential enlnrgement- 11 provided with aserew-threud 1.2 upoxmvhich to screw a nut 13 to bear against the tank-bottom and tighten the trap in its seat.- The trap, which thus'projects for a. short extent of its length into the reservoir through its bottom, conteinsa vertical filling-tube ltwhich is rigid against the inner surface being preferably formed as an integral part of the trap bottom 15) which inclines to a discharge-port 16 in the tube. The cover 17 of the trap, whirl: is provided ventrally with u stuffing-box 18, for the purpose hereinafter." stated, screws at its infernally-threuded circumferential flange 19 about the upper threaded end of the trap against a gasket 20 to hermetically soul the upper end of the tube 14 as well as the trap. This tube contains an inlet-port 21 registering with asiniihu' orl 2]" in the well of the trap adjacent to tie rosm-voir-bottom: and the lower end of the tube, whirh protrudes beyond the trap bottom 15, is internally thirkoned at 23 and provided with u boil-led shoulder forming u ground soul for the valve .25. The valve comprises :1 11 upper lubulur' guidin; svrlion )6 fitting the diun'netrirull w larger sortion ol' the tube H, which forms the valve-raising. and ronhrining o port 28 to register with the port 16. and a narrower tubular svi'tion 27, fitting the thickened tubesertion 23 and open utits lower end and mmtuiuiup u lateral port 29 in its upper end. The two vulvwsertions are separated from (m-h other by on interposed head 30 beveled about its lower end to til the sent 22. The normal position of the valve, whirl; is pro vidod in the upper end of its :iertion 26 with a crosspin ill for the applirution of any suitable hooked implement by which to withdraw the volve out of the 11 )per end of the tube 14-. when unrovered, as or cleaning or repairing it, is against its seat; and in that. position the port registers with the port 16, and the port 29 is closed. A spiral spring 32 is confined about the valve-section 27 between the bottom of the trap and a fork-like stop 33 containing a central exthe trap 10 or inousuring-ohumin-r, whi-h is lushnumod vulvoseotiou at opposite exten preferably a cylindrical Cthfdlg: having 1 ml grooves 35 provided in it. A vent-tube its upper end, a cirabout. I pundod svr'iioii 34 at which it rmbrares the I v fastened at to the cover or head 17.

With the parts in the relative positions in which they are represented in Fig. 1, and the reservoir containing a supply of the liquid for filling packages 7, part of such liquid will have flowed through the ports 21 and 21, the tube 14 and the ports 28 and, 16 into the trap 10, to such height therein as is determined by the distance to which the tube 36 extends into the trap. This tube is intended for gaging the quantity of liquid which enters the trap in accordance with the tapiacity of the receptaole 7 being filled in the operation of the apparatus on a run of packages of the same capacity, such as half-pints, pints, quarts, and so forth; and for determining which quantityshall he admitted to the trap to be discharged therefrom by operating the valve 25 as hereinafter described, the tube 36 is set with reference to the proper mark on the gage being brought coincident with the pointer 39. The liquid which thus enters the trap will therein only to or very slightly' above the lower end of the gage tube, being prevented from rising to a higher level therein by the air-pressure in the air-tight trap, though part of the liquid so introduced will rise above the level in the tube 36, and the quantity of that part is included in the measured quantity for filling the respective capacity of receptacle 7. 'The filling ensues from raising the valve 25 to close the port 28 by taking/it out/of registration with the port 16, thereby to close the trap to the reservoir and; register the port 29 with the port 16, when the contents of the trap discharge through the valve-section 27. This lischargeoperation is produced by the act of pressing by actuating the machine referred to) the top of a receptacle 7 up wardly against thif'stop 33 to raise the valve from its seat to its discharging position, thereby alsocpmpressing the spring 32 to cause it, when released by withdrawing the filled receptacle, to seat the valve and thus restore the apparatus to normal con dition.

It will be obs rved. that the extent of separation of the valve ports 28 and 29 is such as to cause the port 28, in the upward movement of the valve, to clear the trap port- 16 before the port 29 registers therewith. This is an important provision for the measuring function of the apparatus, since it shuts oil the flow from the reservoir into the trap before the dischar e from the in the measurement which would otherwise result. The inclination of the trap-bottom 15 toward the port 16 is another important feature of our apparatus in causing the discharge of the entire contents of the trap. llloreover, the construction, which is very simple, affords such a relation of the parts (valve and filling-tube, and trap and reser' voir) as to enable them to be readily taken apart for cleaning, thereby facilitating a frequent requirement in that behalf, particularly when the apparatus is used for milk.

What we claim as new, and desire to secure by Letters Patent, is

1. In a filling apparatus of the character described, the combination with a reservoir, of a measuring trap depending therefrom having a port in its lower end, a filling tube in said trap having a port in its upper end open to the reservoir, and provided with a port near its lower end whereby liquid from the reservoir may flow through said filling tube into the trap, a double-ported reciprocating valve seated in said tube and having one of its. ports registering, in the seated position of the valve, with the trap-port and its other port registering with said trap-port in the raised position of the valve, said valve ports being in such spaced relation to each other and to the trap port as to close the trap to one before registering, the other therewith as the valve'is moved to its different positions, and means in the trap to vent the same.

2. In a filling apparatus of the character described, the combination with a reservoir, of a measuring trap depending therefrom having a port in its lower end, a filling tube in said trap having a port in its upper end open 'to the reservoir, and provided with a port near its lower end whereby liquid from the reservoir may flow through said filling tube into the trap, a double-ported reciprocating valve seated in said tube and having one of its ports registering, in the seated position of the valve, with the trapport and its other port registering said trap-port in the raised position of the valve, said valve ports being in such spaced relation to each other and to the trap port as to close the trap to one before registering the other therewith as the valve is moved to its different positions, engageable means carried by the valve whereby the same may be removed for cleansing, and means in the trap to vent the same.

3. In a filling apparatus of the character described, the combination with a reservoir, of a depending measuring-trap, a vertical filling-tube in the trap open near its upper end to the reservoir and having an internallythickened lower end protruding through the trap-bottom and forming a latter can begin and thus avoids inaccuracy valve-sedt, a port in said tube above the valve-seat and opening into the trap, and l a valve havin g an upper section and a lower l tubular section separated by an interposed sealing-head and containing a port in the upper section registering with said tubeporl. in the scaled position of the valve and an port in the lower section registering with l l I the trap-port in the raised position of the valve, sairi valve being withdraWa-biy eoniainml in the tube.
